When To Use This
Pro Tip
Position the discharge nozzle pointing toward the ground and away from electrical conduit. When restarting your pump after cleaning, keep the valve open until a solid, steady stream of water shoots out before turning the knob closed—this confirms 100% of compressed air has been evacuated.
Common Questions & Instructions
Which pool filters work with the Pentair 98209800 air relief valve?
This valve is engineered for Pentair FNS Plus D.E. filters, Clean & Clear and Clean & Clear Plus cartridge filters, Predator, Warrior, EasyClean DE systems, and SM/SMBW 4000 series tanks.
Why is water leaking or sputtering from the air relief valve?
Water leakage usually stems from a dried-out internal O-ring, mineral scale build-up in the valve seat, or hairline cracks from sun exposure. If cleaning and lubricating the O-ring fails to stop the drip, replacing the assembly restores a dependable seal.
How should the air relief discharge port be positioned during installation?
Always point the discharge nozzle downward and away from electrical panels, pumps, heaters, and junction boxes. Discharging air and water directly toward energized electrical components creates a severe hazard for electrical shock and equipment damage.
